This was me as a teenager. I didn't get why people wouldn't just choose to be straight - I made that choice every day that I repressed my attraction towards men!

But now it's like, "Wait holy shit there are people who are categorically not attracted to an entire sex?". That's way more wild to me than the idea that people would be attracted to people of the same sex. Imagine seeing a hot guy/gal (tastes accounted for) and just not being into that. Damn.
